In the accompanying drawing indicates a piston rod of an engine, such,

for instance, as a reciprocating steam en- 'gine. 2 is the usual packing .gland surrounding the piston rod and engaging the cylinder head not shown. It has been common heretofore toconnect a cup or casing directly 'to'the outer end of thepacking gland and surrounding the piston rod for containing a swab arranged to engage the piston rod and to deliverlubricant thereto. However, much difficulty has been experisteam is employed, since the heat is sufiicient to char the swab'and thus not only destroy its efficiency but actually/render its use injurious.

A very important advantage of the pres-* ventspieces of swabbing from being drawn by suction from the cylinders into the packin and injuring or'destroying. it.

hat I claim is: v j f 1. The combination, with a pistonrod and a-' packing gland, of a swab container disposed to retain a swab in contact with the piston rod and having heat dissipating fins ,on one side and spacers on its other abling access of air container. 7 I p H 2; .The combination, with a piston rod and a packing gland, of a swab container disbetween the gland and posed'to retain a swab in contact with the piston rod, thesaid container being constructed and arranged to be air and located for enabling access of air between the gland and container, and means bridging the space between the gland and container and including a cap element adapted to overhang the piston rod for preventing access of cinders to the piston rod.

8. The combination, with a piston rod and a packing gland, of a swab container disposed to retain a swab in contact with the piston rod, the said container being constructed and arranged to be air cooled and locatedfor enabling access of air between the gland and container, and means bridging the space between the gland and container for preventing access of cinders to the piston-rod, the said bridging means being formed of sections for permitting free circulation of air.

4. A'swab container for piston rods comprising a container casing, and means extending therefrom adapted'to space the easing from contiguous engine parts when the casing is operatively located relative to a piston rod, the said spacing means being formed to provide a protecting bridge preventing access of foreign matter to the piston rod between the casing and the contiguous engine part.

5. A swab container for piston rods come 30 prising a caslng adapted to sustain a swab Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

inengagement with a piston rod, and air cooling means cooperating with the casing forefiecting distribution of heat therefrom to the atmosphere.

6. A swab container for piston rods comprising a ,casing adapted to sustain a swab.

in engagement with a piston rod,'and air cooling flanges outstanding from the casing.

7. A swab container for piston rods com-V,

prising a casing adapted to surround a piston rod and having "an lnternal annular space adapteclto receive'a swab, and having i I ternal annular space to receive a swab for contact with the piston rod, and spacersarranged to lie between the packing gland and the casing when the latter is in place and being spaced apart to provide air passages between the gland and the casing to cool the latter.
